SU(3)-flavor breaking as a structural probe of hidden-charm-strange tetraquarks in a color-octet basis
Bing-Dong Wan, Jun-Hao Zhang, Yan Zhang +1
We study hidden-charm-strange tetraquark candidates with the exotic quantum number to test whether SU(3)-flavor breaking acts as a universal mass shift or as a stru…

Spectroscopy of hidden-heavy tetraquark states with in a color-octet configuration
Bing-Dong Wan, Jun-Hao Zhang, Yan Zhang +1
Within the QCD sum-rule framework, we investigate hidden-heavy tetraquark channels with the exotic quantum number using four representative local color-octet--octet…
